Lipoic acid helps restore, synchronize the 'biological clock'

CORVALLIS, Ore. – Researchers have discovered a possible explanation for the surprisingly large range of biological effects that are linked to a micronutrient called lipoic acid: It appears to reset and synchronize circadian rhythms, or the "biological clock" found in most life forms. The ability of lipoic acid to help restore a more normal circadian rhythm to aging animals could explain its apparent value in so many important biological functions, ranging from stress resistance to cardiac function, hormonal balance, muscle performance, glucose metabolism and the aging ...

How the brain stabilizes its connections in order to learn better

Throughout our lives, our brains adapt to what we learn and memorise. The brain is indeed made up of complex networks of neurons and synapses that are constantly re-configured. However, in order for learning to leave a trace, connections must be stabilized. A team at the University of Geneva (UNIGE) discovered a new cellular mechanism involved in the long-term stabilization of neuron connections, in which non-neuronal cells, called astrocytes, play a role unidentified until now. These results, published in Current Biology, will lead to a better understanding of neurodegenerative ...

NASA's Aqua satellite sees birth of Tropical Depression 10W

The tenth tropical depression of the Northwestern Pacific Ocean was born as NASA's Aqua satellite passed overhead. NASA's Aqua satellite passed over Tropical Depression 10W on July 17, as it came together northwest of the island of Yap. As Aqua passed overhead the Atmospheric Infrared Sounder (AIRS) instrument aboard captured infrared data that showed powerful thunderstorms developed around the storm's center. When AIRS gathered the data on the cloud tops, the temperatures were already as cold as -63F/-52C, indicating strong uplift has pushed them to the top of the troposphere. At ...

Scientists track gene activity when honey bees do and don't eat honey

CHAMPAIGN, Ill. — Many beekeepers feed their honey bees sucrose or high-fructose corn syrup when times are lean inside the hive. This practice has come under scrutiny, however, in response to colony collapse disorder, the massive -- and as yet not fully explained -- annual die-off of honey bees in the U.S. and Europe. Some suspect that inadequate nutrition plays a role in honey bee declines. In a new study, described in Scientific Reports, researchers took a broad look at changes in gene activity in response to diet in the Western honey bee (Apis mellifera), and found ...

Measuring nurture: Study shows how 'good mothering' hardwires infant brain

By carefully watching nearly a hundred hours of video showing mother rats protecting, warming, and feeding their young pups, and then matching up what they saw to real-time electrical readings from the pups' brains, researchers at NYU Langone Medical Center have found that the mother's presence and social interactions — her nurturing role — directly molds the early neural activity and growth of her offsprings' brain. Reporting in the July 21 edition of the journal Current Biology, the NYU Langone team showed that the mother's presence in the nest regulated and controlled ...

Scripps Florida scientists identify gene that plays a surprising role in combating aging

JUPITER, FL, July 17, 2014 – It is something of an eternal question: Can we slow or even reverse the aging process? Even though genetic manipulations can, in fact, alter some cellular dynamics, little is known about the mechanisms of the aging process in living organisms. Now scientists from the Florida campus of The Scripps Research Institute (TSRI) have found in animal models that a single gene plays a surprising role in aging that can be detected early on in development, a discovery that could point toward the possibility of one day using therapeutics, even some commonly ...

Is the US National Flood Insurance Program affordable?

There is often tension between setting insurance premiums that reflect risk and dealing with equity/affordability issues. The National Flood Insurance Program (NFIP) in the United States recently moved toward elimination of certain premium discounts, but this raised issues with respect to the affordability of coverage for homeowners in flood-prone areas. Ultimately, Congress reversed course and reinstated discounted rates for certain classes of policyholders.

Plasmon-enhanced Polarization-selective filter

As we all know, some optical devices can only work with a certain incident polarization direction. In this case, a polarizer is necessary to shift the polarization direction of linearly polarized light. A common polarizer is also called half-wave plate, which constructed out of a birefringent material (such as quartz or mica). The behaviour of a half-wave plate depends on the thickness of the crystal, the wavelength of light. Considering the fabrication of crystal, a half-wave plate is difficulty to integrate on circuits. Then what kind of polarizer can be integrated on ...
